This is a well-timed article for me. Last night I noticed two small transparent worms on a couple of cuttings I started rooting in moss a couple of weeks ago. I have been scrubbing/bleaching my cuttings -- except for these, which were a last-minute rush job. I figured the worms came in with the cuttings. Now I think it is more likely that they are the babies of a couple of gnats I've seen flying around.
I'm glad to learn that the "not so aptly named fungus gnats" are actually feeding on fig roots and leaves, not just fungus in the soil as their name implies. This motivates me to get rid of the few I have before they become a bigger problem. I don't need yet another thing that can go wrong with getting cuttings to root!
